University of Maryland surgeon Joseph DuBose says Jackson likely died of pneumonia.
Historians and doctors have long debated what medical complications caused the death of legendary Confederate fighter Thomas J. "Stonewall" Jackson, felled by friendly fire in the Civil War.
Jackson's left arm was badly wounded by one of the bullets. It took at least two hours to get him to a field hospital, and Jackson was dropped twice in a stretcher before his arm was amputated.
On Friday, the 150th anniversary of Jackson's death, a trauma surgeon with experience on the battlefield in Iraq and Afghanistan reveals his diagnosis of Jackson's death after re-investigating the medical record.
University of Maryland surgeon Joseph DuBose says Jackson likely died of pneumonia. He is confirming the diagnosis given by Jackson's physician, the famed Confederate doctor Hunter McGuire.
